IPIVOTED AND SLIDING \VINDOW.

Application filed September 19, 1911.

To all whom it may concern Be it known that we, Anvil) TV. EoKnnRe and CARL STOHLBERG, citizens of the United States, and residents of Jamestown, in the county of Chautauqua and State of New York, have invented new and useful Improvement-s in Pivoted and Sliding lVin- (lows, of which the following, taken in connection with the accompanying drawings, is a specification.

The invention relates to window sash constrnction; and the object of our improvement is to provide means for pivotally mounting a sash in a window frame where by it may be held firmly in the vertical position or released so that it may be turned pivotally; and the invention consists in the construction and arrangement of the parts as shown in this specification and the accompanying drawings, and pointed out in the claims.

In the drawings: Figure 1 is a side elevation of a portion of the window sash stile with the pivot mechanism attached thereto in the closed position; Fig. 2 is a fragmentary side elevation of the window sash showing the rear side of the pivot mechanism n the closed position; Fig. 3 is a similar view in the released or open position so that the sash may be pivotally turned within the frame; Fig. i is a perspective view of a portion of the sash and. pivot with the sash pivotally turned; Fig. 5 is a sectional view at line yi in Fig. 2, showing the mechanism for the pivotal connection of the sash with a portion of the window frame; Fig. 6 is a sectional view of the pivot mechanism at line Z-Z in Fig. 2, and Fig. 7 is an end elevation of the pivot mechanism for the window sash.

Like numerals of reference refer to corresponding parts in the several views.

The numeral 10, designates a WlI1(lOW frame, the face of the jamb being provided with parallel spaced grooves 11 in the track of the window sashes 12.

The stiles 13 of the window sashes are each made in tubular form, having a lengthwise groove 14 on the inner edge for the glass 15, sutlicient space 16 being provided around the edge of the glass 15 for suitable packing. The outer edge of the sash stile 13 is provided with a lengthwise groove 17, the edges of the sheet metal being bent inwardly and toward one another to form groove 17, but are preferably a spaced distance apart since Specification of Letters Patent.

it is unnecessary for the strength of the sash that they should be joined. The spaced dis tance between the int-urned edges of the sheet metal in groove 17 permits the painting or otherwise coating of the inside of thetubular stiles and cross rails, and also prevents the condensation of moisture within said tubular stiles and cross rails since the atmosphere is permitted to enter the tubular stiles and cross rails through this opening.

The groove 17 receives therein the lengthwise channel strip 18, which channel strip 18 extends into the groove 11 on the jamb, The outer face of the sash stile 13 is made to fit closely upon the face of the jamb and the groove 11 has sufficient depth to entirely receive the channel strip 18, so that when the strip 18 is moved into the channel 11 the sash 12 may be turned pivotally within the oppositely facing ambs of the frame 10.

In order to'pivotally move the window sash in the frame 10, the channel strip 18 in grooves 11 and 17 is attached at each side of the sash to a pivot bolt 30. The other end of the pivot bolt 3Ov is pivotally attached to an angle piece 31. The angle piece 31 has the slot 32 therein to receive the wrist pin 33 on the cam 3d. The cam 34- has a screw head formation 35 at one side which screw head extends through a hole in the sash stile 13. The angle piece 31 is held in place by suitable side pieces 36 so that it may slide back and forth freely therebetween and be neath their turned edges. It is now appar cut that the screw 35 may be manually turned by a screw driver or other means thereby turning cam 34 and moving angle piece 31 and pivot 30 and so moving channel strip 18 out of or into the lengthwise channel 17 in the sash stile 13. The channel strip 18 preferably extends the full length of the sash stile 13 or a sutlicient length to firmly hold and brace the metal sash. It is also obvious that when the channel. strip 18 is moved out of the channel 17 in the sash stile and into groove 11 on the frame 10, the sash 12 may be turned pivotally in frame 10, as shown in Fig. 4, and that when the sash 12 is returned to the vertical position and the strip 18 is moved out of the amb groove 11 and into the groove 17 in the sash stile, the channel strip 18 will hold the sash firmly at each side of the sash 12 against pivotal movement and at the same time will form a simple and efiicient weather stop in the joint between the sash stile 13 and the jamb of the frame. It is on this account that the channel strip 18 is preferably made the full lengthpofthesash stile 13. It is also ap parent that the sash 12 is free to slide up and down in the window frame 10, the channel pieces 18 sliding easily and forming a guide Within the grooves 11, and that at any point within the window frame when the sashes 12 are free from one another, the sashes may be released from the support of channel strip 18 and pivotally turned in the window frame.

to the jamb groove, a strip transversely movablein said grooves, and means to actuate the strip including a pivot bolt secured.

to the strip, an angle piece having the pivot bolt passlng through 1ts outstandlng member, guides for the base member of the angle piece to permit the latter to slide back and go forth, said base member of the angle piece having a slot therein, and a cam having a Wrist pin which projects into the slot of said base member. 1

2. In a window sash construction, a jamb having a lengthwise groove therein, a sash having a lengthwise groove therein located opposite to the jamb groove, a strip movable in said grooves, and means to actuate the strip including an angle piece which is 40 slidable transversely with respect to said grooves, a pivot bolt connected to the outstanding member of the angle piece and to the strip, means carriedby the sash to slidingly mount the base of said anglepiece,

and means connected to the said base of the angle piece for sliding the latter.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
